SOLE-SPLITTING MACHINE.

SPECIFICATION forming part of Letters'ratent No. 570,164, dated october27, 189e.

Application tiled May 1, 1894. Serial No. 509,733. (No model.) l

To cr/ZZ whom, it may concern.-

Be it known that LFRANCIS JOSEPH FREESE, of the city of Montreal, in thedistrict of Montreal and Province of Quebec, Canada, have inventedcertain new and useful Improvements in Sole-Splitting Machines; and I dohereby declare that the following is a full, clear, and exactdescription of the same.

This invention relates to machines for dividing thick sole-blanks into anumber of thinner soles, and has for its object to overcome certainobjections in the present machines,`among which may be mentioned thetendency through the use of a pair of feeding-rolls to shear offport-ions or diminish the thickness of the soles at some points owing tothe blanks failing to keep in true horizontal position on issuingfromthe feed-rolls, and, further, to secure an accurate feed.

The invention consists of the several devices and combinations ofcpart-s hereinafter described and claimed. f

For full comprehension, however, of the invention reference must be hadto the 'annexed drawings, forming a part of this specification, in whichlike symbols indicate corresponding parts, and wherein- Figure l is aside elevation of the machine with framing partly broken away; Fig.- 2,a plan view of same; and Fig. 3, a vertical sectional elevation on lineFig. 1.

ce is a suitable supporting-frame or hollow structure with aclosed topa', and furnishing suitable bearings-for a horizontal drivingshaft b, avertical counter-shaft c, and a short vertical stub-axle d.

The driving-shaft h in addition to carrying at its outer end the usualfast and loose pulleys ef also carries a pulley g, from which a belt istaken to a smaller pulley h on the shaft h/ of a fan j, inclosed in anopen-ended curved casing or conduit 7c, thus constituting a suctiondevice for a purpose to be presently mentioned. The casing k has thenecessary bearings 7e 7c for the shaft h', formed in one with it, and issuspended from the under side of the top d' of the frame, so that itsupper open end will communicate with an opening a2 in such top ct', itslower open end communicating with or projecting through an opening inthe side of the frame, as shown in Fig. 3.

The inner end of the driving-shaft b carries a worm l1 to intermesh witha pinion on the' lower end of the vertical counter-shaft c, and thislatter shaft in turn carries 'at its upper end another pinion orspur-gear c/ to i11- termesh with a gear-wheel CZ near the lower end ofthe stub-axle cl. The upper end of this stub-axle d carries thetraveling table :or carrier, preferably in the form of a circular diskZ, perforated, as at throughout an annular section thereof,on which thesole-blanks are placed. Suitable butting-stops Z2 are also yplaced onthe surface of the table in the posi- .suitable bracket p2 to a pulley qon the shaft h of the suction-fan.

A second standard 0', superimposed upon the standard m, furnishes abearing for an intern ally-screw-threaded sleeve r', the upper end ofwhich is provided with a suitable handwheel and the lower end receivingthe screwthreaded upper end of a sliding shaft r2 freely coupled at itslower end, as at s, with the top of the shaft n and fitted in a squaredbearing r3, so that the shaft ot can be rotated without rotating thisshaft r2 or the sleeve fr', while the shaft n can be raised or loweredby the rotation of the sleeve to adjust the knife nearer to or fartherfrom the table according to the thickness of sole to be out.

The yielding resistance to act upon the upper side of the blank as itnears the knife is preferably in the form of a roller t, carried in thelower ends of an inclined rocking frame t', pivoted at t2 to brackets u,depending from the standard m and impelled toward the table by means ofretractile springs o with their ends secured, respectively, to thebrackets 1l, and the side arms of the frame t.

In the operation of the machine the blanks are placed on the table overthe perforations and in front of the stops, as shown in Fig. 2, theknife being adjusted to the required position relatively to the table byrotating the IOC adjusting hand-wheel, and as the table revolves theblanks are carried beneath the yielding pressure-roller t into contactwith the knife, the edge of the blank being prevented from turningupward, as is the natural tendency, by means of the suction through theapertures beneath it.

XVhat I claim is as follows:

l. In a sole-splitting machine, the combination With the cutter orknife, of a feed device in the form of a horizontally-rotatingperforated table or carrier, a yielding resistance device in the form ofa plain roller with spring-controlled support therefor adapted to bearupon said blanks as they approach the cutter and a suction device actingupon a limited number of the perforations in the ta- .ble with means foroperating the cutter and feed, for the purpose set forth.

2. In a sole-splitting machine, the combination With the cutter andmeans for adj usting same, of a feed device in the form of ahorizontally-rotating perforated table or carrier, a yieldingresist-ance device in the form of a plain roller with spring-controlledsupport therefor adapted to bear upon said blanks as they approach thecutter, and a suction device acting upon a limited number of theperforations in the table, with means for operating the knife and feedfor the purpose set forth.

In a sole-splitting machine, the combi nation of the cutter, aperforated traveling table or carrier for the blanks, a suction devicehavin g a single tube, the mouth of which acts directly beneath theperforations in said table, and means for operating same, for thepurpose set forth.

l. In a sole-splitting machine, the combination of the cutter, aperforated table or carrier revolving in a horizontal plane capable ofcarrying a number of blanks, a suction device having a single tube, themouth of Which acts directly beneath the perforations in said table andmeans for operating same, for the purpose set forth,

5. In a sole-splitting machine, the combination of the cutter, means foradjusting same, a perforated traveling table or carrier for the blanks,a suction device having a single tube, the mouth of which acts directlybeneath the perforations in said table communicating only with a limitednumber of the perforations at a point in advance of the cutter and meansfor operating same, for the purpose set forth.

G. 'In a sole-splitting machine, the combination of the cutter, aperforated traveling table or carrier for the blanks, a suction devicehaving a single tube the mouth of which acts directly beneath theperforations in said table, communicating only with a limited number ofthe perforations at a point in advance of the cutter, a yieldingpressure device and means for operatin g the cutter, table and suctiondevice for the purpose set forth.

7. In a sole-splitting machine, a feed device in the form of aperforated traveling table and a suction device havinga single tube themouth of which acts directly beneath the perforations in said table andonly upon a limited number of the perforations therein.

8. In a sole-splitting machine, the combination with the inclosingcasing having an opening in its upper side, of the cutter, the means foradjusting same, the revolving perforated feed-table above said easin gand travcling across the opening in the upper side of the casing, thesuction-conduit communicating at its upper end with said openin g and atits lower end withlthe outer air, the suctionfan Within said conduit;the yielding pre.- sure device adapted to bear upon the blanks carriedby the table as they approach the cutter and means for operating theWhole as and for the purposes as set forth.
